IMPROVEMENT IN R'OUNDABOUTS.

Specification forming part of Letters Patent No. 196,753, dated November6, 1877; application filed April 4, 1877.

To all whom it may concern: A

Be it known that I, HENRY H. HAWTHORNE,

of the city and county of Philadelphia, State of Pennsylvania, haveinvented a new and useful Improvement in a Seesaw and Roundabout, whichimprovement is fully set forth in the following specification, referencebeing had to the accompanying drawings.

The object of my invention is ,to provide a oted in the center betweenthe open jaws of a swivelpiec'e, B, which is supported upon a stand, 0.D D are horse-heads, of wood, and E E are seats at each end of the beam,the horse-heads being furnished with handles F F,

' which are grasped by the occupants of the seats to insure a safe andsteady position. G

- G-are gum pads or springs secured at the extremities of the beam toform cushions and compensate for the sudden jar when the ends of thebeam are brought in contact with the floor or ground surface, and alsoto prevent injury to the carpet when the seesaw is set up in a furnishedroom.

The horse-heads D D and seats E E at each end of the beam are secured toflat bars H H which are connected by means of the pivotpins 19 p to barsI I- on the lower edge of the beam. The pivot-pins pass loosely throughthe beam, and connect the bars H and I at or near their rear ends, sothat the horse-heads may be swung out at right angles, or nearly so, tothe beam when a change to a roundabout is desired.

J J are vertical supports hinged to the front ends of the bars H H, andcarrying at their extremities the wheels K'K and foot cranks or treadlesL L. M M are hooked rods or braces attached to the sides of the beam,and engaged with openings n n in the bars I I, to

' hold the same when swung outward, as shown in Fig. 2.

When the parts are to be used as a seesaw, the supports J J, with thewheels K K, are

closed up against the lower edge of the beam,

as shown in Fig. 1, so as not to interfere with the vibration of thesame. In this position they are held by any suitable device.

In changingfrom a seesaw to a roimdabout, the bars H and I are openedout, as shown in Fig. 1, and the supports J J placed in their propervertical positions, the hinged joint being arranged so as to maintainthem in this position. The occupants of the seats grasp the handles F Fon the horse-heads to insure a steady position, and, placing the feet onthe cranks, communicate motion to the wheels, and thus propel themselvesaround and around in a large circle.

The pin of swivel B rests loosely in a metalh'c socket, N, secured inthe stand 6, so that the swivel will revolve freely when the beam isoperated as a roundabout, or permit of the beam being readily separatedfrom the stand for convenience in transportation.

What I claim as my invention is 1. The combination of the beam A,horseheads D D, seats E E, handlesFF, gum pads or springs G G, centralpivot B, and stand C, operating as a seesaw, substantially as hereinshown and described. v

'2. The combination of the beam A, horseheads D D, seats E E, handles FF, bars H and I, pivot-pins p 1), vertical supports J J, wheels K K,cranks L L, hooked rods M M, swivel B, metallic socket N, and stand O,operating as a roundabout, substantially as herein shown and described.

3. The beam A, pivoted to the stand 0 to rotate in a horizontal plane,in combination with the horse-heads D D and seatsE E, projecting atright angles, and provided with vertical supports J J, wheels K K, andcranks L L.
